Definitions

  • the present invention refers to a device for evaporating volatile substances, comprising a porous mat impregnated with volatile substances and a heating element that heats the porous mat for evaporating said volatile substances.
  • Standard technology for the heater construction deal about either an electrical heater embedded in a ceramic casing or a nude electrical resistor placed inside a plastic housing.
  • the ceramic casing and the plastic housing have the function to assure electrical insulation between the resistor and the surroundings.
  • the heat not directed towards the wick or porous mat promotes a general heating of the device that can rise substantially the temperature of the surface of the device. This is the reason why the devices use to have a considerable dimension in order to avoid the temperature at the surface exceed a limit defined by electrical certification entities.
  • bigger dimension of the device is a limitation for portability.
  • the objective of the present invention is to provide a device for evaporating volatile substances that permit to direct substantially all the heat provided by the heating element to the porous mat, preventing an excessive rising of the temperature of the surface of the device.
  • the device for evaporating volatile substances according to the present invention comprises:
  • a heating element that heats the porous mat for evaporating the volatile substances, and a reflective element for reflecting the heat from the heating element to said porous mat, wherein the reflective element forms a cavity defined by a bottom and side walls where the porous mat and the heating element are placed.
  • the reflective element is formed from a metal sheet, e.g. from a mirror sheet.
  • the cavity formed by the reflective element comprises one or more seals for making the cavity airtight.
  • the cavity airtight is having a certain level of vacuum, preferably from 0.1 -0.2 bar.
  • the heating element is a ceramic heater.
  • the porous mat is placed on the heating element, and the device also comprises a printed circuit board where the reflective element is mounted, and the printed circuit board is preferably fed by a battery.
  • the device for evaporating volatile substances according to the present invention also comprises a grill that covers the porous mat, through which the volatile substances can evaporate and that also serves as a protection against accidental contact with the porous mat, which is hot during its use.
  • the porous mat can comprise a holder for facilitating its handling.
  • the reflective element reflects or redirects the heat radiation from the heating element back towards the porous mat where the volatile substances are impregnated, and the heat energy that is going away from the porous mat is reflected back to the porous mat, so that a heating element which consumes less energy can be used for the same evaporation capacity.
  • the cavity formed by the reflective element is airtight, a more efficient heating of the porous mat is achieved. This is especially of interest for portable devices that can be exposed to uncontrolled situations where dirt may be introduced accidentally inside the device. Any matter present in the cavity will affect heat transfer, due on one side to its thermal inertia, and on the other side, due to its interaction to heat transfer irradiation between heater and reflective material.
  • Fig. 1 is an exploded perspective view of the components forming the device for evaporating volatile substances according to the present invention.
  • Figs. 2 and 3 are perspective views during the placement of the porous mat of the device for evaporating volatile substances according to the present invention.
  • the device of Fig. 1. is an example of portable device, with the highest level of requirement for a portable device, as it is a band wrist mounted device.
  • the requirement as anticipated earlier are: to be lightweight, to be adequate to be use in areas where dirt or water can be present, and to have low level of external temperature of the housing.
  • the device for evaporating volatile substances comprises a porous mat 1 which is impregnated with volatile substances, such as fragrances or insecticides, and a heating element 2 that heats the porous mat 1 for evaporating the volatile substances.
  • the heating element 2 is any suitable heating element, but according to a preferred embodiment it is a ceramic heater, having a flat shape as shown in Fig. 1.
  • the porous mat 1 has also a flat shape and preferably comprises a holder 7 that facilitates its handing, because the porous mat 1 is used as a refill, so that it can be replaced once all the volatile substances have been evaporated.
  • the porous mat 1 is placed on the heating element 2 with a distance between them.
  • the device according to the present invention also comprises a reflective element 3 for reflecting the heat from the heating element 2 to the porous mat 1 , and the reflective element 3 forms a cavity defined by a bottom and side walls where the porous mat 1 and the heating element 2 are placed.
  • the reflective element 3 is formed from a metal sheet, e.g. a mirror sheet, and the cavity formed by the reflective element 3 comprises one or more seals 8 for making the cavity airtight.
  • the seals 8 are four, each placed at the corners of the cavity, which has a rectangular plan.
  • the device for evaporating volatile substances according to the present invention also comprises a printed circuit board 4 where the reflective element 3 is mounted, leaving a gap between the printed circuit board 4 and the reflective element 3.
  • the printed circuit board 4 is fed by a battery 5, that can be connected to the mains for recharging it.
  • the printed circuit board 4 heats the heating element 2 placed inside the cavity defined by the reflective element 3, and this heating element 2 heats the porous mat 1 for the evaporation of the volatile substances.
  • the assembly of the printed circuit board 4, the reflective element 3 and the heating element 2 are mounted inside a housing 11 , which can have a watch-like shape, comprising a closure 10 for accessing to the battery 5.
  • the housing 11 also comprises a grill 6 which is hinged to the rest of the housing 11 for permitting the insertion and the removal of the porous mat 1 .
  • This grill 6 also has the function of protecting the users from contacting accidentally the heated elements.
  • the grill 6 is mounted on an intermediate housing 9 that surrounds the reflective element 3.
  • a porous mat 1 must be placed in the use position, as shown in Figs. 2 and 3, and the device must be switched on.
  • the battery will feed the printed circuit board 4, which will heat the heating element 2.
  • This heating element 2 will heat directly and indirectly the porous mat 1 , and all the heat from the heating element 2 will be concentrated and reflected to the porous mat 1 by the reflective element 3.

Abstract

Le dispositif d'évaporation de substances volatiles comprend un matelas poreux (1) imprégné de substances volatiles, un élément chauffant (2) qui chauffe le matelas poreux (1) pour l'évaporation des substances volatiles et un élément réfléchissant (3) pour réfléchir la chaleur provenant de l'élément chauffant (2) vers ledit matelas poreux (1), l'élément réfléchissant (3) formant une cavité définie par un fond et des parois latérales dans laquelle le matelas poreux (1) et l'élément chauffant (2) sont placés. Grâce à cette caractéristique, l'élément réfléchissant (3) réfléchit ou redirige le rayonnement thermique de l'élément chauffant (2) vers le matelas poreux (1) dans lequel les substances volatiles sont imprégnées, et l'énergie thermique qui s'éloigne du matelas poreux (1) est réfléchie vers le matelas poreux (1), de telle sorte qu'un élément chauffant (2) qui consomme moins d'énergie puisse être utilisé pour la même capacité d'évaporation.
